Because of the street-cat problem we have (they mark everything in our yard! ARGH!), I set up the tree on the front end of our bike before hosing it off.
This is my normal mode of transportation with the kids: They both sit up in the carrier frame where the tree is. Let me tell you, this bike is heavy, and cycling around 30kgs of kids is not easy. :P I don't know how much longer I can do it.
If you look closely, you can see brakes along the handlebars. They don't work. The peddle in the up position in this photo is actually almost exactly in line with the footbrake. Very tricky to get used to, especially since you have to hike your leg pretty high to use it.
